2 Claims.

My invention relates to the class of devices that are employed for cooling purposes, more especially for lowering the temperature of rooms used for living purposes, and an object of my inven- 5 tion, among others, is the production of a cooling apparatus that shall be simple in construction and particularly efficient in operation.

One form of a device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing in which Figure 1 is a View in front elevation of my improved cooling apparatus.

Figure 2 is aside view of the same.

Figure 3 is an isometric perspective view of the receptacle for ice, partially broken away to show construction.

For the purpose of relieving oppressive conditions in apartments or rooms used for living purposes electric fans are commonly employed and while these are partially eective they do not relieve the conditions to such an extent asis desired for the reason that they simply produce a circulation of the air and the temperature of the Aair is not affected. I am aware that means have heretofore been employed for reducing the temperature of the air circulated by electric fans but the means employed are unsatisfactory for the 3o reason that the full benefit of the cooling medium is not obtained and the drip of moisture from the cooling medium is also objectionable. Such apparatus as I have mentioned employs regular ice as a cooling medium and by reason of such use and the moisture resulting from it, it has been impossible to place the cooling medium in the most advantageous positions to get the maximum result therefrom.

I have found that an apparatus equipped for 40 the use of dry ice as the cooling medium possesses most desirable features, as owing to the absencel nof the formation of moisture the receptacle for the cooling medium may be placed in a position e to obtain maximum results in the lowering of temperatures in compartments or rooms employed for living purposes. Such an apparatus is shown in the drawing herein in which the numeral 5 denotes in general an electric fanof common construction and comprising abase 6, a fan 1 mounted on a shaft, 8 connected with Il circular in form braced by tie wires I I and supported by arms I2 secured to and projecting in.

(ci. az-91.5)

radial directions from the motor 9, as shown in Figs. 1 and 2 of the drawing. All of the parts thus far described are of common and well-known construction and a more detailed description is therefore omitted herein.

U-shaped brackets I3 bridge the space between the rims III, the branches of said brackets being secured to the rims as by means of clamps I4 secured in place as by means of screws, as shown in Fig. 1 of the drawing. A receptacle or chest 10 I5 is secured to the brackets in any suitable manner and has a door I6 preferably attached to the receptacle as by means of hinges with a lmob I'I as a means for securing the door closed. The receptacle or pan has a perforated bottom I8 1 upon which the cooling medium comprising a piece of dry ice is placed. 'I'he top 20 of the receptacle also has perforations 2 I. These provide means for effecting a circulation of air from within the receptacle and it is my intention that 20 the perforations may be arranged in many different ways and that that shown in the drawing need not necessarily be followed in detail so long as they are so arranged that a circulation of air from the receptacle downwardly to the fan is caused, 25 thereby circulating the air throughout the room or compartment within which the same may be placed. The bottom of the pan is perforated so that air may drop from within the receptacle about the fan, there being no danger of drip of 30 moisture from the ice owing to its characteristic of producing no moisture to drip therefrom.

4denotes the ice.

It will be seen from the foregoing description, taken in connection with the accompanying 35 drawing, that with a piece of dry ice within the receptacle and the fan in operation the cool air from within the receptacle will fall in front of and about the fan, the perforations in the receptacle readily accomplishing this effect, and the air 40 will be blown by the fan in a direction away from it and thereby circulate the same throughout the compartment.

I claim: l

1. A cooling apparatus comprising an electric 45 fan of the type having a wire guard for safety purposesfand a receptacle adapted for use with so-called dry ice, said receptacle being closed on its four sides and having a perforated top and bottom on the latter of which the ice is placed, 50 said receptacle `being supported on said guard close to the upper edge of the fan whereby the 2. A cooling apparatus comprising an electric fan of the type having a wire guard including a circular rim, brackets secured to said rim on opposite sides of its vertical cross wise center, and

5 a receptacle mounted on said brackets with its bottom substantially against said rim in close proximity to the periphery of said fan, said receptacle having a perforated bottom for the support of so-called dry-ice whereby water free air is circulated in all directions by said fan directly from within said receptacle.
